Patent DE-4003944-A1 (DE)
Title: New synthetic polypeptide conjugate of LHRH and keyhole limpet haemocy - used to provide antibodies to hormone, for treating breast and prostate carcinoma etc.
Inventor: PRINZHAUS GERHARD DR
IPC: C07K14/59
Filed: 1990-02-14
Abstract: A new synthetic polypeptide has the formula LH-RH-KLH. LH-RH = luteinising hormone releasing hormone. KLH = keyhole limpet haemocyanin. Only the synthetic hormone provokes a specific immune reaction, with specific antibodies, to human LH-RH, thus antagonising the biological action of LH-RH. Conjugates of LH-RH with other naturally occurring haemocyanins (e.g. limulus haemocyanin) with the same effect, are also claimed. USE/ADVANTAGE - The antibody inhibits the action of LH-RH on the hypophysis, arresting hormone release and therefore preventing gonadotropic secretion, resulting in reduced hormone (e.g.  oestrogen or testosterone) synthesis. The synthetic polypeptide is therefore useful in the therapy of receptor-positive breast and prostrate tumours and is cheaper than known alternatives, as it is easy to synthesise.

Title: Support frame for oven baking trays - in which frame is fitted with height-limiting plate above each baking tray and plates can be adjusted by moving single lever
Inventor: HUTH HEINZ D DIPL ING
IPC: A21B3/15
Filed: 1990-03-05
Abstract: A number of cover grills corresp. to the number of baking trays used, are attached to a frame and can be raised and lowered by means of a lever. The grills may be supported by a frame and adjusted in height by a mechanism which pulls them down against the force of the spring. Alternatively, the grills may be raised by a crank acting against the lowest member of the support frame. The adjustment may be arranged by operation by a foot pedal. The grills can take the form of perforated or profiled metal plates, and may be used to form a pattern on the tops of the bakery prods. USE/ADVANTAGE - Certain bakery prods. are such as to require a limitation in height during baking, and the customary procedure of placing special plates above each baking tray and hand to achieve this effect is very time consuming.
